Hello,
i am trying to remember a game i played in my childhood on a Windows 2000-Windows XP Computer.
It was around the time Warhammer 40k was released.
The game was a sci-fi realtime strategy game similar to red alert 2 or starcraft.
It mainly played on alien planets and you were been able to build electric or steel walls in order to protect your base.
The graphic was already 3d - but more simpler with mainly smooth, round surfaces.
If i remember correctly the name of the desktop shortcut ended with "2K" and included some space-themed name.
The Logo of the game included 2K or 2000 too.
The game had multiple fractions and many of them were been mecha and metal style building, vehicels.
It also had a solo campain with real-artist video secuences where also weird dressed actors (depending on the fraction) were been in action and spoke into the camera.
One of this fractions were been some "sacrifice" type with weird body modifications.

I think that were been all things i can remember for now.
